Aging
The term aging can be critically understood as a progressive physiological changes in an organism that gradually leads to senescence, or a decline of biological functions and declination of the organism’s ability to adapt to the metabolic stress. Aging evidently takes place in a cell, an organ, or within the total organism with substantial passage of time. Aging is a process that continues over the entire adult life span of any living organism. Gerontology is correctly referred to the study of the aging process, the study is devoted towards the intricate and detail understanding and controlling of all factors that are found to contribute to the finitude of an individual’s life.Gerontology is not exclusively and predominantly concerned with debility, which looms quite largely among the human experience, instead of that it deals with a wide range of phenomena. The process of aging is the sequential and/or progressive change in an organism. The process gradually leads to an increased risk of debility, disease, and eventually death.
